FPS Drop On Approach!

Recommended Posts

I can not put my finger on why this happening.

Example flight:

Aerosoft Airbus

Take off from ORBX Queenstown

Scenery is ORBX NZ South Island

Active Sky Next

REX including Soft Clouds

 

On runway i get appx 30FPS

In flight flickers between 20-30

On Approach to Christchurch default airport 15FPS and feels awful

Traffic is off

 

I have the sliders about 2/3rds right

 

Process explorer sas I have used about 2500 VRAM

GPU-z says never above 600mb of my 2GB card

 

I have tried different bufferpools including zero

I have tried different water settings

 

I have an i5 clocked to 4.3

8GB Ram

Win 7

 

As per the readings, doesn't seem that the pc or graphics card is stressed at the time anyway

 

I have this issue on other flights but because this is a nice short flight, i can test better

Any ideas please?

is your destination full of autogen? Did you try to reduce it? Did you modify LOD radius? Is the weather different there? how many cloud layers you have in ASN? What about max and min visibility and cloud draw distance? Do you have road traffic on? Or everything road and airline is 0?

Destination full of Autogen? It's the default airfield with ORBX New Zealand, so no, not really.

LOD Radius, not even looked at that, so that will be default, is it wrth looking at ?

6 Cloud layers but even adjusting it during flight makes no obvious difference to FPS

The weather is slightly different but I would say for the better as it is less cloudy

MAX and MIN both default at 90 miles

There is no road traffic or any other traffic

 

Thanks

Try minimum visibility 60 max 100 and 4 cloud layers. 4 is max you see irl in 99% cases and clouds make huge difference. what is your water setting? what is your anti aliasing? Forced through nvispector? Dx9 or dx10? Do you have similar issue outside of region?

My water setting has been the source of my latest tinkering.

 

If I turn my water setting off, i do get an increase, so I changed my Bufferpools from 0 to different settings but no better, so went back to zero, hwoever it mean si have to have water at high 2x i think it is.I have turned it back down a little but i get flashes which is expected.

 

Anti aliasing is done by nvidia inspector but am at work so cannot say what it is.

DX9

I will try the visibility you mention and 4 layers. Why is the default 5 if the max we actually see is only 4?

 

Thanks for your help

In rare cases you can see 5 but I remember reading this info straight from HiFi forum. Why? No clue but default 5 was performance killer to me. 4 is smooth even with enhanced overcast so there is something going on for sure. The aa can also kill performance but than again since it is approach specific in your case - might not be the main culprit.

That FPS loss on approach is a typical DX9 problem, main reason I switched to DX10 with the Fixer = no FPS loss at all. DX9 is very prone to stutters and drop of fps, didn't found the cause yet. As far as I can remember when I was using DX9 mode, on every approach I changed scenery or autogen complexity usually one step lower, and fps was way better, at least for a couple of minutes.

Not really considered DX10, maybe worth a look if everything else fails

Just my 2 cents worth.   As an experiment (and this has worked for me in the past), save your flight at base leg/finals, and exit FSX completely.   Start the Sim and load your flight.   As you proceed for the final minutes of your flight, how do the frames look?   Not a nice way to complete a good journey, but it may help you assess where the problem lies.

That's what I was thinking when was on DX9, but now I will rather delete FSX than back to DX9. DX10 is smooth, no bugs,no problems with VAS, no fps drop, better visuals.

A totally inaccurate post. Thousands of us use DX9 and don't get a FPS loss on approach.

I actually forgot about one thing - is your win 7 64 or 32 bit?

It doesn't matter because FSX is a 32 bit program.

 

Edit: What we really could be looking at is his FSX.cfg file and see if the necessary tweaks have been applied.

 

Also we should see if his CPU is running at full speed through the BIOS and through any utilities.

That was my experience with DX9 with various hardware configurations. As soon I switched to DX10 all these problems went away, so it's logical for me to blame DX9.

Ahh. so typical for you and not for the community!

 

I hope that statement about stutters and a FPS drop was typical for you and not for the community also!


I have 64bit

 

I have MEMFIX, BUFFERPOOLS, VSYNC (Window Mode) tweaks added

Any other obvious ones I have forgotten?

CPU affinity?

I saw I lot of similiar posts about fps drop and stutters in DX9, but of course not all simmers have this issues, FSX is a strange beast. :) I had that bad luck to experience every single DX9 culprit, sadly. The only cure for fps drops that I've used is to change LOD or scenery complexity during flight, it seems that is a some kind of a memory leak problem.

I agree, I've never even tried DX10 but my frames remain constant on approach. The only time there might be a small drop is when the airport scenery and AI start filling in as I approach.

It does regarding VAS. On 32 bit after 3 GB you face crash therefore in the range of 2.5 slowdowns may be visible. Maybe I confused it but I think this was the case in many situations?

Your statement *IS* accurate.  Just because other community members have had no problems with DX9 does not mean DX9 is not the cause of the slow down.  When I used Steve's DX10 Fixer it brought new life to my poorly performing DX9 garbage heap.   It ran far smoother, crashed far less often and that was without me having to tweak anything that the DX10 Fixer didn't do on its own.   It made the experience far more hassle free and allowed me to prolong the life of FSX for a while longer.     DX9 works for some, great.  Good for you.  Dismissing DX9 as the culprit on other people's system though is silly as it CAN be a giant performance murder machine on certain hardware setups and improperly balanced simulation settings.  DX10 is far more forgiving for those who don't have a software engineering degree in futility.

Hi,

 

I have very similiar problem… fps drops (to about ~10) on approach. After landing, when taxi to the gate, fps sometimes back to normal (about 25 fps). For example it happens on arrive to payware EPKK or freeware EDDF…

 

Sometimes there is another issue – on approach, FSX freezes once but on several seconds! (it not responding). It looks like it has to load huge amount of scenery data (?)

For example it often happens on approach to payware DDesign EPWA + Warsaw City sceneries.

After this freezing, there is also fps drop.

 

I have Windows 10 and FSX:SE (I don’t have FSX box and FSX:SE was installed on clean Windows). I use DX10 mode with DX10 Fixer. I fly only on PMDG aircrafts.

 

Other addons: ORBX Global, Vector, OpenLC_EU, FreeMeshX, REX4, ASN, FSFX Precipit and Immersions for PMDG aircrafts, WoAI traffic and vPilot to connect VATSIM, FSCaptain, GSX, FS2CREW, EZCA.

 

Hardware: i5 2500K@4.3 GHz, 8GM RAM, GTX660Ti 2GB.

Hi Friends,

 

any ideas? :sad:

Hi Lucas,

 

Good news and bad news:

 

Good) NZCH is known to be extremely heavy on performance for an unknown reason. So it is not an issue with you sim/setup. Even on the highest power rigs it still drops to 10-20 FPS.

 

Bad) Orbx have decided that they are not going to bother updating it so we just have to live with it. Christchurch is my hometown but even I refuse to fly there in P3D because of the above issues.

Maybe should I set UsePools=0?

 

Many people say that it improve fps even in SE...

 

What about AffinityMask? In "classic" FSX I had it set with value =14. Maybe in SE it is also needed...?
